FOREWORD 

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire Fighting 
Sectional Committee had been approved by the Civil Engineering Division Council. 

This standard permits the use of copper, copper alloys, aluminium and aluminium alloys only in the manufacture 
of couplings, and it is strongly recommeneded that all the components be made in either aluminium or its alloys 
and copper or its alloys as it is essential to avoid, as far as possible, coupling aluminium alloy to copper alloys 
or vice versa, particularly for long periods, or otherwise electrolytic action may result from the close proximity of 
these metals to each other. It is also recommended that aluminium alloy fittings be made from gravity die- 
castings, unless otherwise approved by the purchaser. On die-cast fittings, where the bore is shown as parallel, 
it is suggested that the manufacturer be allowed a resonable taper to facilitate core withdrawl but this taper 
should be kept to the minimum required for this purpose. Other materials may be used with the prior approval of 
the purchaser provided that they have good corrosion resistance to all types of water, including sea water or 
brackish water, and there is no change of electrolytic action between adjacent materials. It is also essential that 
aluminium alloy couplings are thoroughly washed with fresh water immediately after use with sea water or 
brackish water. 

The Composition of the Committee responsible for the formulation of this standard is given in Annex A. 

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, 
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 
IS 2 : 1960 *Ruies for rounding off numerical w^lucs (revised)*. The numbers of significant places retained in the 
rounded off value should be the same as that of the specified value in this standard.
